Vl'ith these and other objects in View, as

will inoi'e tullyi1 appeall as the description proceeds:l iny invention furthermore consists and combine.w tions ott parts, as will be described and claiin'ed in the appended claims.

ln the manufacture of beds or, trames for horizontal engines and the liliea complete diliiereiit set o patterns is usually reqnireil for the lnannjt'aoture of each sine of engine;

`the general practice being even to make a nenT set of patterns for manufacturing for instancea Aa double cylinder engine having` each cylinder ol" the same capacity as that of the correspOndinev single cylinder engine, .in order to `save space and unnecessary Weight. ln Sonie casesD in order toproduce a double cylinder itinere bodily connect twojcoinplete single cylinder engines with the result that the cost of the neiyengine `and the space occnpied by the saine are virtually twice as ninch as isitlie case with the single cylinder engine. n

All the above methods of manufacture result ilouone reason or the other in high cost evident that it dit- 'feient patterns and tools are used "tor di'- tel'entsizes of engines, not only is the .first and tools high', but the productioimntZ engines not" ditlferent capacities is not as Well adapted; for quantity produc-- tion under economical conditions as the case where said engines are made ontoll sets of duplicate parte. Since it is always desirable; howeveryto have elementary unit engines 'for at leasta few cylinder diniei'isioiri amil `corresponding capacities, the improve inonts 'forming the `object of the present in- Ventioii may lie-said tojbeinoie particularly directell tothe l'constructioni oli l'oii-ineiloli two onmore" units of the saine capacitynin `which, as heretofore stated, coni siderable economy oit cost and space Ina-y be obtained. i

The main reason Why inany manufacturers pieten to constructseparate engines intheir enti i'ety,` fendi to provide therefore icon'iplete sets oli drawings,patterns and tools :tor cach inane engines engineN some inanuiacl engine, when manufacturing single, double and three Cylinder engines having the saine piston, diameter and stroke, rather than to connect together Atwo-or three complete engines, lies in the fact that a double cylinder engine made from a special set of patterns, for instance, occupies less space, weighs less and altogether costs less than an yengine of the same capacity obtained by connecting together two single cylinder engines.

4lt is apparent, for instance, that in the latter casev it is necessary to machine Vfour bearings, .two in each frame as against three in the former case. n, y

By means of my improved unit construction of multiple cylinder engine, l am able to retain all the advantages of quantity production, at the same time, also retaining i all the advantages of saving in space and coinpactness pertaining to the manufacture of multiple cylinder engines with different sets of patterns for each engine; l am in other words able to obtain a multiple cylinder engine costingv lessA than an engine of the saine capacity obtained by connecting together twoor more single cylinder engines andl also costing less than an engine hai/ing the saine number of cylinders made from a special frame, which does not at the saine time occupy any more space than the latter type oit engine would occupy.

i lVith my invention I am also ablel to produce an engine to which a new unit can always be added withthe addition of only one bearing, said. new unit being caused to interlock or to connect with the( former in a predetermined way, causingv said new unit 'to remainin a known and. definite relation to the old one and to remain automatically in perfect alignment and ready for the mounting of a new crank shaft and such other parts as may be necessary to provide to comply with the rci'yuirements of the new capacity of the engine.

In the annexed drawings l. illustrate by way of example aA few multiple ,cylinder engine beds embodying my invention and in the same- Fig. 1 is a plan view partly broken away of a double cylinder oil engine;

A multiple cylinder engine constructed according to my invention generally coinprises a main unit which is a single cylinder engine complete with two bearings and accessories including devices for cani shaft suitable devices provided in the main unit, ff'

and all that is necessary to do when a ucw unit is added is to provide a longer cani shaft or to extend the existing cam shaft to the required length, the controlling devices remaining absolutely the saine. turally calls for a construction of main unit which departs to al certain extent from the general practice 'inasinuclras the cani shaft runs transversely to the engine, while ou the ordinary type of machine the cani shaft is longitudinally arranged.

Referring to the drawings, Fig. l a. plan view of a two cylinder oil engine cousisting of a main unit bed l and an additional unit bed 1l; details of the saine arc also shown in an enlarged scale in Figs. El, 4L- and 5. l2 designates the air compressor, 13 a longitudinal shaft mounted on thc end unit controlling the cani shaft lll, and l designates the crank shaft. Cani sha lt lll is mounted, as shown, in front ol cylinder heads 16, 1.7 and receives motion from controlling shaft 1,3 through the incdiuin ot mitre gears 18, 19.

The main unit engine bed lll is provided with two main bearings 2l), Ql aud llicsc are secured to its foundation by means of foundation bolts Q2. Main bearing Qi. has a portion 23 overhanging from the trame, which, while the head unit is working as a single cylinder' engine. is not subject to any considerable stresses, the crank boing located between the two bearings and the in ner portion of the bearings being supported by the main body of the frame. As soon as a new unit ll. however, provided with an outer bearing 2l. is added at thc side ol' bearing 2l, the ovcrha-nging portion Q3 of said portion 2l becomes directly subject to the stresses in bothdirections coming from the cranlrlocuted between said hearing Q1 and bearing 2e. It is quite possible to build said overhang'ing portion 23 sullicieutly strong to withstand said stresses without any considerable deformation, but l prefer This nay inname `case surfaces y and 27 are concentric to the surface of bearing 2l and' can tl'ierefore be machinedsimultaneously with` said bearing by means of a suitable boring and turning tool. The corresponding portion of the chined so as to form with said overhangingi bearing portion 23` and groove. 26 a male `and female joint as clearly illustrated: in

Fig. 3; in this manner the stressesenerted against the rear part of bearings 2lwill be taken up by the rear portion ofshoulder 27 and by the `portion of the additional unit abutting against the rear part of `surface 25', while in the same manner the stresses dlrected against the front part of bearing' 2t will bel taken up by the front portion of surface 2?' and by the portion of the addiv"tional unit `frame abutting againstthe front portion of`surface25.

The male and female jointfbetweentwo adjacent units described, however, fills `furthermore"a most `necessary function. in

respect to that portion of the Vadditional.

` unit frame which interlocks with theputer bearing ,of the other unit.` By observing; the drawings, it will be seen that morder to make room' for the overhanging portion `23 of the bearing itisinecessary to conlsiderably weaken the section of the addisection apart.

tional unit frame interolckingi` therewith,

the weakest section being directly under they center of said bearing. Fromwthis it fol-` lows that the tensile stresses taking place in the frame between thebearings` andy the cylinder during" the compression and explosion periods, tend t0 spread said `weakened It is very necessary, therefore, that means be provided to prevent this spreading of the frame and this duty effectively fulfilled by that partoffthe 4niain portion of the jointfwhich interloclzs with the portionof `groove 26 located between'the bearings' and cylinder.

bolts 28, and if necessary by means of addii tional bolts 29. 30 designates the oil well which is provided in the bearng for pun` rposesof lubrication, and 3l designates suitable oil `,epreuves provided in the bed ltrames in' order to collect the oil coming from the bearings and the cylinder and other' parts `ef the engine. i

`Each additional unit is also secured to the foundation by means of foundation bolts adapted to be inserted through holes v32, which are located at the inner side of the additional unit close to fthe space where over cylinder engine is obtained which doesl `not occupy any more space than a corre'spending,I multiple cylinder'engine made as a single unit. i,

Additional unit ll may or may not be machined 'to provide further additions; and in the drawings, Fig. l, the same is shown as being machined so that `a new unit may be added if desired, asishownqin Fig- 2 where` a unit 33 has beenadded to form a three cylinder engine. i I

ln the caseof anoil `engine Vit will generallybe sufficient `to change the strolrefof thecompressor piston in order to malte the original compressors serve for the new enA gine capacity, so that generally the only .changes vthat will be necessary will be in the crank shaft and in the cam shaft. `The flywheel may also have to'be changed, but ofcourse a construction of flywheel` 'to which additional elements may be added to render the samie suitable for different capacities may be easily conceived.

ln Figut, l show a modified form of 'joint between two units where each unit ispro vided with a groove 262126 and the joint `is effected by means of an element Bel serted within said two grooves as well asby hanging,portion 23 of bearing 2l, projects. -The maximum compactness in the result- Y ing structure is thus secured and a multiple additional `unitframe is accordingly ma- .Y

causing, as before, the outer part of the beary Y ing 23 to register with the body of the additional unitframe at 25.` .i

Itis obvious that the various details of construction may be modified to a considerone side only, since it is obvious that a member similar to the one applied at one side of thc original unit may with suitable modifications be simultaneously applied at the other side.

The drawings are intended merely to convey the fundamental idea on which my finvention is based, and l reserve myself the right to put my invention into practice in all `those. forms and manners which may be CTI deemed best in each particular oase and which may enter fairly into the Ascope oi"- thefappended claims.
